In the past, carburetor-to-EFI conversion was no picnic. At the very least, you would need a laptop and significant tuning experience. But thanks to FAST™ engineers, those days are over. With the new EZ-EFI® Self Tuning Fuel Injection System, you get patent-pending EFI system technology that does all the work for you. Simply hook it up, answer the basic setup Wizard questions on the included hand-held display, and the system tunes itself as you drive!

The new EZ-EFI® Self Tuning Fuel Injection System provides you with the complete EFI system package, including the ECU, wide-band O2 sensor, wiring harness, fuel injectors, an optional fuel pump kit and other assorted components, including the innovative 4150 Throttle Body from FAST™. This cast throttle body gives you the total package for your existing 4150-type manifold and comes with everything, including the appropriate fuel injectors and fuel rails.
